Re: [Haskell-cafe] what is a stack overflow?

Thank you iavor. But the -K option doesn't appear to work with ghci. And I guess the bigger question is what sort of code causes a stack overflow. If 5M is enough stack for most programs then I obviously have some basic coding error which is causing a stack overflow... What sort of code causes that? -Alex- ______________________________________________________________ S.

hi, programs compile with GHC have a bunch of command line switches. you can see them by typing: myProg +RTS -help one of them enables you to specify stack space, e.g. myPorg +RTS -K5M

(very briefly) the stack is a part of memory used by the compiler to pass around arguments to functions, and for temporary computations. -iavor

GHC assumes the user knows the difference between the heap and the stack. I don't. No matter how much heap I specify on the GHCi command line, I get a stack overflow exception. I have no idea what that means or how to remedy it. Hints?

Note: My program is basically creating a few 100k item FiniteMaps. I don't think that should exceed the memory on my laptop....
